Quaternary ammonium compounds in hypersensitivity reactions. [PDF]
Front Toxicol, 2022 Quaternary ammonium compounds (QAC) are commonly used disinfectants, antiseptics, preservatives, and detergents due to their antibacterial property and represent the first used biocides before phenolic or nitrogen products. Their common structure consists of one or more quaternary ammonium bound with four lateral substituents.

Ammonium compounds in stratospheric aerosols [PDF]
Tellus B: Chemical and Physical Meteorology, 1986 The circumstances under which morphological examination can provide a reliable guide to thecomposition of stratospheric particles are discussed. It is then shown that while stratosphericparticles often consist largely of sulfuric acid, there are occasions when ammoniated aerosols arepresent.
